Drug(s) whose efficacy can be enhanced by this phytochemical
Hide/Show
Combination Pair ID: 474
Pair Name Oxidized tea polyphenol, Nimotuzumab
Partner Name Nimotuzumab
Disease Info [ICD-11: 2C25] Lung cancer Investigative
Gene Regulation Down-regulation Phosphorylation AKT1 hsa207
Up-regulation Expression BAX hsa581
Down-regulation Expression BCL2 hsa596
Down-regulation Expression EGFR hsa1956
Down-regulation Phosphorylation GSK3B hsa2932
Down-regulation Phosphorylation MAPK1 hsa5594
Up-regulation Cleavage PARP1 hsa142
Down-regulation Phosphorylation STAT3 hsa6774
In Vitro Model NCI-H1781 Minimally invasive lung adenocarcinoma Homo sapiens (Human) CVCL_1494
In Vivo Model NCI-H1781 cells (5 × 106 cells per mice) were subcutaneously injected into the flank of each nu/nu mice. 3 days later, the mice were treated by intraperitoneal injection OTP-3 and nimotuzumab (three times per week) for the indicated period.
Result OTP-3 can also serve as an effective therapeutic agent in NSCLC where it can augment the effects of nimotuzumab, a valuable property for combination agents.
Combination Pair ID: 878
Pair Name Oxidized tea polyphenol, Sildenafil
Partner Name Sildenafil
Disease Info [ICD-11: 2C60] Breast cancer Investigative
Biological Phenomena Induction-->Blockade of cell cycle in Sub-G1 phase
In Vitro Model MCF-7 Invasive breast carcinoma of no special type Homo sapiens (Human) CVCL_0031
MDA-MB-231 Breast adenocarcinoma Homo sapiens (Human) CVCL_0062
Result Sildenafil, in combination with flavonoids, may be considered a novel strategy for cancer treatment.
